The results indicate that the cooling rate of melt droplet that can not break further depends not only on its diameter, but also on its position in atomizing chamber. As a result, the same sized particles in different positions show different cooling rates and two different kinds of microstructures. The cooling rates of melt droplets range from 104 to 108 K/s, and the critical cooling rate for glass formation of Al-Ni-Y is about 105 K/s. Moreover, the corresponding maximum diameter of amorphous particles is 25 μm, which accords well to the theoretical analysis results. The new approach, reflecting the complexity of close-coupled gas atomization objectively, is available and effective to evaluate the cooling behaviors of close-coupled gas atomization.
